Electricity can be made from fossil oils ,like coal, lignite etc when it is burned it can produce electricity otherwise in some hydraulic systems the oils used in it can also produce electricity
Not exactly. Petrol (called "gasoline" in the US) is made only from petroleum, the black crude oil which is pumped from the ground and is considered a fossil fuel. Maize (corn) can, however, be used...
No, because the components that make gasoline are already distilled from the crude oil at the refinery to make same. Motor oil is made from a base stock that's removed separately.
